In this section, we will adopt an iterative approach, which can be called bulk cell gluing method [1]}, [2]}, combined with the convex duality technique from the theory of convex optimization to prove that there is always a bit thread configuration that can lock any set of specified non-crossing regions and satisfy the “CFF=PEE” constraint at the same time, such that it can be used as a holographic qubit threads model.
